l ll-IANDICRAFT TOOL BACKGROUND OF THE INVENTION 1. Field of the Invention This inventionrelates to a handicraft tool for knotting cut piles or loops one by one onto each of filaments of a separately prepared basic meshed material having meshed filaments, and more particularly to a handicraft tool which is suitable for making a rug, carpet, a tapestry, or the like by knotting a plurality of cut piles to filaments of a separately prepared meshed basic material.

2. Description of the Prior Art:

It is known as a handicraft to make atapestry, carpet,

rug, or the like by hooking yarn to a meshed basic material by using a tool resembling a knitting hook. The conventional tool has an opening-closing portion at the tip which is angularly movable relative to a portion for hooking the yarn. Itis necessary in this prior art arrangement, however, to carefully watch the movement of the opening-closing portion relative to the hooking portion. The conventional tool has another shortcoming: namely, its hooking portion tends to inadvertently catch the yarn and filaments of the meshed material. Thus, special skill and long experience is required for successfully operating the conventional tool. Other shortcomings of the conventional tool are that a weaver or hooker must visually check the conditions of the opening-closing portion thereof throughv the entire cut pile making operation, that the tool must have a long shaft because the opening-closing portion opens outwardly, and consequently the cut-pile making operation with the conventional tool is rather slow due to the foregoing limitations.

Therefore, an object of the present invention is to mitigate the aforesaid difficulties of the conventional handicraft tool, by providing an improved handicraft tool which facilitates high-speed knotting of a plurality of cut piles to a separately prepared basic material.

SUMMARY OF THE INVENTION A, handicraft tool by knotting cut piles one by one to each of filaments of a meshed basic sheet material, according to the present invention, comprises an elongated hollow handle consisting of a recessed bottom member and a lid-detachably secured to the bottom member so as to cover-a recessed portion of the bottom member. A reciprocating member is disposed in the recessed portion of the bottom member, a button secured to the reciprocating member, a slot formed throughat least one of the bottom member and the lid. The button extends through the slot in such a manner that the reciprocating member can be actuated by operating the button from the outside of the handle. A pair of resilient hook levers each has one end connected to the reciprocating member, and a sleeve is secured to the handle, said pair of hook levers extend through said sleeve so that tips of the hook levers extend to the outside of the sleeve. The hook levers and sleeve are related in such a manner that the tips of the hook levers are separated from each other when the reciprocating member is forwarded toward the sleeve, while the tips of the hook levers engage with each other when the reciprocating member is retracted away from the sleeve.

With the handicraft tool according to the present invention, one or more cut piles are carried by the sleeve thereof, and the tip of the sleeve is passed. into one of the meshed-holes of a separately prepared basic member or foundation. The button of the handicraft tool is reciprocated, so as tohold a part: of the cut pile by the closed'tips of the hook levers. Thus the cut pile can be knotted to a filament of the basic sheet material by simply pulling the sleeve out of the mesh hole while holding the cut pile by the tips of the hook levers.

Thus, the handicraft tool of the present invention is very simple in operation, yet it ensures very quick knotting of a plurality of the cut piles onto the basic sheet material, without requiring any special skill.

In one of preferred embodiments of the present invention, a bobbin-like grooved cassette carrying yarn wound thereon is selectively mounted on the sleeve of the handicraft tool, and the wound yarn is cut along a groove of the cassette, so as to provide a plurality of cut piles onto the sleeve upon removal of the cassette therefrom. Thereby, the knotting of the cut piles to the basic material is accelerated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A handicraft tool according to the present invention, as shown in FIGS. 1 to 7, comprises an elongated handle l, which handle includes a recessed body 2 with a stepped portion 3 formed at the front part of the body and a recessed portion 4 formed at the rear part of the body. A lid 5 is secured to the body 2 by a screw 6. A hollow space 7 is formed through that portion of the body 2 which is located in front of the stepped portion 3, and a hollow sleeve 8 is fitted in the hollow space, so that the inside space of the handle 1 communicates with the outside thereof through the hollow space 7 and the sleeve 8. A pair of guide walls 9 are formed in the recessed portion 4 in symmetry with each other relative to the longitudinal center line of the sleeve 8, as can be seen from FIG. 3.

The lid 5 has a slot 10, which is bored therethrough in alignment with the space between the two guide walls 9. The front edge of the slot 10 may be aligned with the stepped portion 3 of the body 2 when the lid 5 is in position mounted on the body 2 in position. A slider 11, as shown in FIG. 4, is fitted in the space between the two guide walls 9, so as to slide along the walls 9. A T-shaped groove 12 is formed on the bottom surface of the slider 11, as shown in FIG. 4. An operating button 13 is integrally formed with the slider 11, in such a manner that, when the slider fitted in the recessed portion 4 between the guide walls 9 and the lid 5 is mounted in position on the body 2 in position, the button 13 extends-through the slot 10 out of the handle lat the upper surface thereof. Thus the slider can be reciprocated back and forth by manually actuating the button 13.

Referring to FIGS. 1 and 3, a pair of leaf-spring hook levers 14 are disposed in the-body 2, so as to extend through the sleeve 8. Rear end portions of the hook levers 14 are fitted in the T-shaped groove 12 and the very rear edges 16 of the two hook levers 14 extend away from each other in that portion of the T-shaped groove 12 which is perpendicular to the longitudinal direction of the sleeve 8. Thereby, the'two hook levers 14 are resiliently fixed to the slider 11, so that the hook levers move together with the slider 11. Free ends of the two hook levers 14 form a hook. The free ends 15 of the two resilient hook levers 14 are bent e.g., in the form of V-shape, so that, when the slider 11 is moved to its front or forwarded position, the two free ends 15 as separated from each other, so as to open the hook, as shown in FIG. 1. On the other hand, when the slider 11 is moved to its rear or retracted position, the two free ends 15 engage with each other so as to close the hook, as shown in FIG. 3. The closed hook of the two ends 15 ofthe hook levers 14 is located at the front end of the sleeve 8.

The manner in which the handicraft tool of the invention is operated will now be described, by referring to FIGS. 5 to 7. A length of yarn e.g., of wool is folded at about the midpoint thereof to form an open loop or cut pile a, and the folded portion is carried by the sleeve 8 of the tool, shown in FIG. 5. The free end portion ofthe sleeve 8 is inserted in one of the mesh openings 22 of a separately prepared meshed basic material 21, which may be made of a suitable flexible substance, such as comparatively soft synthetic resin. In the illustrated embodiment, the meshes 22 of the basic material 21 are defined by filaments 23 extending in two orthogonally extending directions. In FIG. 5, the folded portion of the cut pile a is located under the sleeve 8 of the handicraft tool, and the free end of the sleeve 8 extends further to pass underneath a filament 23 between two adjacent mesh holes 22. After moving the slider 11 forwardly for opening the hook defined by the free ends '15 of the hook levers 14, the two leg portions of the folded cut pile a are extended over the filament 23and fitted in the open hook, as shown in FIG. 6. As' the slider 11 is retracted, the hook is closed by the rearward movement of the hook levers 14, so that free ends 15 of the levers at the hook firmly hold the leg portions of the cut pile a. In this case, the oppositeends 17 of the pile a are aligned, because the pile a is folded at the midpoint thereof. When the handle 1 of the handicraft tool is moved away from the aforesaid portion of the filament 23, a loop b of the pile a is formed atthe folded portion thereof, as shown in'FIG. 7. The two leg portions of the pile a pass through the loop b, while being held by the hook of the handicraft tool. The pile 2 can be securely knotted to the filament 23 by strongly pulling the handle 2 of the tool away from the filament 23. After the knotting, the slider 11 may be moved forwardly again, so that the hook is opened by the separation of the two front ends 15 of the hook levers l4, and the cut ends 17 of the pile a'may be tufted, relative to the basic material 21, shown at the left-hand side portion of FIG. 7.

Thus, with the. handicraft tool of the present invention, the cut piles a can be knotted to the basic material 21 very easily and very quickly, without necessitating any special skill.

FIGS. 8 to 13 illustrate another embodiment of the present invention, in which like parts as those of the preceding embodiment are designated by like numerals and symbols, and only those parts which are different from the preceding embodiment will be described here. The only difference of this embodiment from the preceding embodiment lies in that two horn-like projections 18 are provided on opposite sides of a sleeve 8, so as to define a pair of pile holding portions 19 be tween the sleeve 8 and the horn-like projections 18, as shown in FIG. 8. Referring to FIGS. 11 to 13, the position of the cut pile 1 relative to the sleeve 8 is fixed by holding the two legs of the folded cut pile a by the pile holding portions ,19. Specifically, as the-two-legs of the pile a are held by the hook of tips 15 of two hook levers 14 and pulled away from the filament 23 of the basic material 21, the folded portions of the cut pile a are automatically removed from the portions 19 of the handle I 1. Otherwise, the construction and the operation of theembodiment of FIGS. 8 to 10 are the same as those of the preceding embodiment, as described in detail by referring to FIGS. 1 to 7,

FIGS. 14 to 22 illustrate a third embodiment of the present invention. A sleeve 8 extends forwardly from the front end portion of a handle 1, and two arms 31 extend in parallel to the sleeve 8 on opposite'sides thereof, as shown in FIG. 16. A pair of pile holding grooves 33 are formed by the sleeve 8 and the arms 31 so as to extend along the opposite sides of the sleeve 8. Each of extended ends 32 of the arms'31 is bent toward the sleeve 8, but terminates with a spacing therefrom. An auxiliary sleeve 34 of elongated thin reed shape is extended from the tip of the sleeve 8, as shown in FIG. 16. A pair of resilient hook levers 14 extend from a slider 11 with an operating button 13 to the outside of the auxiliary sleeve 34 through the hollow space 7 of a body 2, the sleeve 8, and the inside of the auxiliary sleeve 34 itself. The extended tips 15 of the resilient hook levers 14 form a hook for selectively holding the cut pile a, in the same manner as the similar hook of the preceding embodiments. More particularly, the tips 15 of the levers 14 move away from each other to open the hook when the operating button 13 is at a front or forwarded position, while as the button 13 is moved back to a rear or retracted position, the tips 15 engage with each other to close the hook.

The pile holding grooves 33 are characterized in that a rectangular grooved bobbin or cassette 35 can be selectively fitted therein, as shown in FIGS. 15 to 17. The cassette has an inverted-Ushaped channel groove 36 at the bottom thereof. A U-shaped top groove 37 is formed at the top of the cassette 35, for receiving a cutting edge for severing piles, as will be described hereinafter. The side walls of the top and bottom grooves 37 and 36 have cutaway portions 39, 38, respectively. Woolen yarn 41 is wound on the cassette at the cutaway portions 38, 29, as shown in FIG. 16. V-notches 40 are provided on the side walls of the top groove 37, so as to hold the opposite ends of the woolen yarn 41, as shown in FIGS. 15 and 16. The spacing between the two cutaway portions 38 and 39 determine the length of individual cut piles to be knotted to a basic material. The length of the cutaway portion 38 or 39, taken in the longitudinal direction of the groove 36 or 37, does not exceed the length of the pile holding groove 33, as measured in the longitudinal direction of the sleeve 8.

The function of the cassette 35 will now be described. After the woolen yarn 41 is wound, the cassette is mounted on the handicraft tool by fitting the side walls of the bottom groove 36 on the sleeve 8, as shown in FIG. 17. A cutting edge, such as a scissors c, is inserted in the top groove 37, so as to sever the top portions of the wound loops of the thick woolen yarn 41. It should be noted in FIG. 17 that bottom portions of the wound loops of the yarn 41 extend underneath the sleeve 8. Accordingly, when the cassette is moved vertically upwardly after severing the yarn 41,

as seen in FIG. 18, the cassette 35 itself can be separated from the handicraft tool, but a plurality of cut piles aof substantially uniform lengths are left in the pile holding grooves 33, as shown in FIG. 18. The spacing between the sleeve 8 and the arm 31 is such that the cut piles a can be held in a row while keeping the side portions of the piles substantially upright.

After being loaded with the cut piles a, the tip of the auxiliary sleeve 34 is applied to a separately prepared meshed basic material 21, so as to scoop the filament 23 of one mesh 22 of the material 21 onto the auxiliary sleeve 34, as shown in FIG. 19. In this case, the button 13 may be held at the rear position for keeping the tips 15 of the hook levers 14 in engagement with each other, so as to facilitate the scooping of the filament 23. After the scooping, the button 13 is moved forwardly v for separating the tips 15 of the two hook levers away from each other, so that two side portions of the foremost cut pile a can be inserted in the space between the thus separated tips 15 of the hook levers 14, as shown in FIG. 20. Then, the button 13 is retracted to its rear position, so as to cause the tips 15 of the hook levers 14 to engage with each other while firmly holding the side portions of the cut pile a, and the handicraft tool itself is moved away from the filament 23, as shown in FIG. 21. As a result, the bent or folder portion of the cut pile a is removed from the pile holding grooves 33, and the side portions of the pile a carried by the tips 15 of the hook levers 14 pass through a loop b defined by I the folded portion of the pile and the filament 23, so

that the pile a is knotted to the filament 23. Upon knot ting, the button 13 is move forwardly again, so as to release the side portions of the cut pile a. Cut ends 17 of the thus knotted piles a may be tufted, as shown in FIG. 22.

FIGS. 23 and 24 illustrate a modification of the handicraft tool of FIG. 14, by replacing the reciprocating button with. a swingable button. In this embodiment, the body 2 of a handle'1 has a side slot 44, wherein a stationary pin 45 is secured, and a sector-shaped swingable button 42 is pivoted to the body 2 by fitting a pivot hole 43 of the button 42 on the pin 45. The button 42 has two arms; namely, one arm 46 which is kept outside the handle 1 and another arm 47 disposed within the handle 1. The arm 47 fulfills the function of the slider 11 in the preceding embodiment, as shown in FIG. 1. More particularly, inner ends 16 of a pair of hook levers 14 are secured to the arm 47 of the swingable button 42. In addition, one end 51 ofa coil spring 50 is secured to the inner arm 47 of the button 42. The other end 48 of the spring 50 is secured to a raised portion or boss 49 which is integrally formed with the body 2 of the handle 1. The coiled spring 50 acts to normally keep the inner arm 47 of the swingable button 42 at its forwarded position so as to keep tips 15 of the two hook'levers 14 separated. At the same time, the spring 50 urges the button 42 clockwise, as seen in FIG. 23. Spaced stop projections 52, 53 are provided on the outer arm 46' of the swingable button 42, so that the angular movement of the button 42 is limited by the engagement of the stop projections 52, 53 with a stopper 54 which is integral with the body 2 of the handle 1. Apart from the aforesaid structure of the button 42and the related mechanism, the embodiment of FIGS. 23 and 25 has similar a construction similar to that of the just preceding embodiment, as described in detail with regards to FIGS. 14 to 22.

Referring to FIG. 16, when a bobbin-like cassette 35 carrying woolen yarn 41 wound thereon is going to be mounted on pile holding grooves 33 of the embodiment of FIGS. 23 and 24, it is preferable to keep the tips 15 of the hook levers 14 engaged, i.e., to keep the hook closed. To this end, the swingable lever 42 is turned counter-clockwise by pushing the arm 46 toward the body 2, so that the other arm 47 of the swingable button 42 is moved to its retracted position for pulling the hook levers 14 inwardly to the body 2 and closing the hook at the tips 15 thereof. After mounting the cassette 35 on the pile holding grooves 33, 'the'swingable button 42 may be released. It is apparent that a plurality of cut piles a can be formed on the grooves 33 by using a cutting edge and by removing the cassette 35 away from the body in a direction perpendicular to a sleeve 8, in the same manner as the preceding embodiment. The knotting of the cut piles a to a separately prepared meshed basic. material 21 can be perfomed substantially in the same manner as in the case of the preceding embodiment, as described in detail hereinbefore by referring to FIGS. 19 to 24. The one difference is that the retracting movement of the button 13 of FIG. 14 is replaced with the inward turning of the swingable lever 42 of FIG. 23, and the forwarding movement of the former button is replaced with the resilient outward return of the latter button. The resilient return of the swingable button 42 may simplify the knotting operation, as compared with the manual forwarding of the reciprocating button 13.
